Bosnia and Herzegovina is burdened with one of the world’s most severe land mine problems as a result of the four years of hostilities from 1992 to 1995 that left an estimated two million unexploded landmines and munitions scattered in 28,699 locations throughout the country. In one district in the northeast of the country, Posavina Without Mines (PWM), a humanitarian, non-profit NGO, is under contract with the government of the District of Br?ko to warn residents of mined areas by permanently marking suspected contaminated areas, removing the lethal objects, and helping mine-affected victims.
